MDX report rendering takes long time and showing Conflict Message

Question

Hi All,
This is my MDX Query
with member
[Measures].[Rent] as
IIF(IsEmpty([Measures].[Budget]),
NULL, [Measures].[Rent])
select {[Measures].[Rent]}
on columns,
                     [Property].[Address].[All].children *
         DESCENDANTS([Account].[Account Hierarchy].[Account Group].[Expenditures],
                     [Account].[Account Tree].[Account]) *
                     [Property].[Property].[All].children
on rows
from
   [Master]
When i comment [Property] Dimension member , i am able to get the result, but i need Property Dimension in MDX.
Can anyone give some idea ?
Thanks in advance

Hi Jarugulalaks,
According to your description, it take long time to render the report when using [Property] dimension, right?
In this case, the issue can be caused by that there are too many members under this dimension. In your query, you used CrossJoin function to join multiple dimensions which might cause the performance issue. If you cross-join medium-sized or large-sized sets
(e.g., sets that contain more than 100 items each), you can end up with a result set that contains many thousands of items—enough to seriously impair performance. You can use the NonEmptyCrossjoin function instead of Corssjoin function. For the detail
information, please see:

Besides, the total time to generate a reporting server report can be divided into 3 elements: Time to retrieve the data (TimeDataRetrieval); Time to process the report (TimeProcessing); Time to render the report (TimeRendering). For the detail information,
